.SH NAME
\fBRtlUniform\fR (NTDLL.@)
.SH SYNOPSIS
ULONG RtlUniform
 (
  PULONG \fIseed\fR
 )

.SH DESCRIPTION
.PP
Generates an uniform random number. 

.SH PARAMS
\fIseed\fR \fB[Out]\fR  The \fIseed\fR of the Random function.
.PP

.SH RETURNS
.PP
It returns a random number uniformly distributed over [0..MAXLONG-1]. 

.SH NOTES
.PP
Generates an uniform random number using D.H. Lehmer's \fB1948\fR algorithm. In our case the algorithm is: 
.br
  result = (*seed * 0x7fffffed + 0x7fffffc3) % MAXLONG;
.br

.br
  *seed = result;.

.SH DIFFERENCES
.PP
The native documentation states that the random number is uniformly distributed over [0..MAXLONG]. In reality the native function and our function return a random number uniformly distributed over [0..MAXLONG-1]. 

.SH IMPLEMENTATION
.PP
Declared in \fB"winternl.h"\fR. 
.PP
Implemented in \fB"dlls/ntdll/rtl.c"\fR. 
.PP
Debug channel \fB"ntdll"\fR.
